Homebrew PCBs

Hi Tod,

I thought I'd look at the Excellon files, they should have the hole 
data.  Somewhere is a program to convert that to Gcode.  Just having the 
coordinates and drill sizes should do it.  If I can import points into 
Vector CAD/CAM, I can generate a Gcode program.

So that's what that was on my HC-49 crystal!  I turned off the vrestrict 
layer, and the extra went away.  Didn't seem to help anyway, I had a via 
(that I've since moved) encroaching into this area.

Just tried a solpad.  Must be a test pad?  I almost forgot to add some 
test points.

It seems to get harder to find the un-routed signals at the very end. 
Is there a way to make them stand out, or determine their net name?
